  • Electric Radiator Fan Recommendations for a 2003 GMC Sonoma
  • Adding an electric fan or fans is subject to how much space you have in the engine compartment. The first thing I would check is if your 2003 Sonoma has a fan driven by a serpentine belt (a belt that turns the pulleys of several components) or if it has its own belt. If the fan is attached to the pulley for the water pump, you will not be able to remove it though the blades may be able to be removed. So if you find that your fan or blades can be removed and you can add an electric fan,...

  • Troubleshooting Damaged Trailer Wiring Harness

The video linked at right shows how to use the tester. It sounds like you may have connected multiple lighting circuits to...

  • The Magnetic Tow Lights, # RM-2120, plug directly into a 4-Way flat connector on the tow vehicle.

  • How to Install Hand Crank Brake Winch in 2001 GMC Sonoma to Pull Go-Cart Up Ramps
  • The best type of winch for your application is a brake winch like # F143100 from Fulton or one of the others shown on the linked page. These automatically brake when you stop cranking; this will prevent a runaway cart.

In order for any winch to deliver its rated performance it must be mounted to a suitable surface and have its bottom plate fully supported by...
